What is the principal quantum number for an electron in the ground state of a hydrogen atom?

What is the principal quantum number for an electron in the ground state of a hydrogen atom?

Step 1: Understand what a hydrogen atom is. It is the simplest atom, consisting of one proton and one electron.
Step 2: Learn about quantum numbers. They are numbers that describe the properties of electrons in atoms.
Step 3: Identify the principal quantum number (n). It indicates the energy level of an electron.
Step 4: Know that the ground state is the lowest energy state of an atom.
Step 5: For hydrogen, the ground state corresponds to the principal quantum number n=1.
